However, native Americans 26 very much like Chinese or Mongolians and are called American Indians. No one knows 27 how long ago it was when the first persons came from China. 28 the first Europeans came only four hundred years ago.Most of the first European immigrants(移民)came from 29 . They named some of their first cities 30 their homeland. There is a city called York in England so they 31 an American city and a state New York. 32 is an island named Jersey so they named a state New Jersey. 33 English names inAmerica are New Hampshire and Pennsylvania, named after a 34 Englishman named William Penn. All of the early 35 together were called New England and they have that name today.Other Europeans soon 36 the English immigrants. There were Germans and Dutch from northern Europe and Italians and Spanish from 37 Europe. The French settled more in the north Canada.Since England is really four countries in 38 , there were four types of people 39 came. There were English, Irish, Scottish and Welsh from England, Ireland, Scotland and Wales. Some of these 40 settled in Canada.This 41 of many people together became 42 as a melting pot(熔炉). The pot is where cooks make soup and when soup is 43 , all the foods become melted together. A country known as a melting pot is more 44 than one which has had a long history with 45 immigrants.26.

A. mixing B. fixing C. thinking D. discoveringToday,I want to talk to you about the historic opportunity we now have to protect our nation’s children from an e ven more deadly threat:smoking.Smoking kills more people every day than AIDS,alcohol,car accidents,murders,suicides,drugs and fires combined.Nearly 90 percent of those smokers lit their first cigarette before they turned 18.Consider this:3 000 children start to smoke every day illegally,and 1 000 of them will die sooner because of it.This is a national tragedy that every American should be honor-bound to help prevent.For more than five years we’ve worked to stop our children from smoking before they start,launching a nationwide campaign to educate them about the dangers of smoking,to reduce their access to tobacco products,and to severely restrict tobacco companies from advertising to young people.If we do these,we’ll cut teen smoking by almost half over the next five years.That means if we act now,we have it in our power to stop 3 million children from smoking and to save a million lives as a result.49.What has the author done in his power?A.To look after our children.B.To clean the street.C.To teach our children.D.To protect our children from harm.pared with other disasters,what kills more people every day?A.Smoking.B.Car accidents.C.Drugs.D.Murders.51.How many children start to smoke every day illegally?A.1 000.B.3 000.C.90.D.18.52.For more than five years what have they done to stop their children from smoking?A.To educate them about the dangers of smoking.B.To reduce their access to tobacco products.C.To restrict tobacco companies from advertising to young people.D.Above of all.CThe American cigarette companies are worried that the anti-smoking campaign(运动) is catching fire and the U.S. government may issue(发布) stronger regulations about the use of tobacco.Many governments and private buildings have “No Smoking” regulations(规则).In airplanes,on trains and at cinemas,Golf courses are seriously thinking of keeping out smokers,so are schools,shopping malls and even football fields.So where do people go to fill their lungs with nicotine?The government is working on it.One suggestion is that the government set aside a piece of land somewhere in the United States where smokers could go when they want a cigarette.Yellow Stone Park has been on the list,but many people don’t agree because they fear that second-hand smoking would make the bears there sick.The Mojave Desert in California is also being studied,and so are Las Vegas Casinos(拉斯维加斯赌场).The smokers were not too nervous about the government idea.They say they are not going to California just to light up.They have a right to smoke at home.Tomake life more pleasant for those who find it hard to give up smoking,the government is seriously thinking of getting somewhere for the smokers.The officals in the government say they realize that they are bringing trouble to people by making them go so far away to blow smoke rings.But they just had to do this or to ban(禁止) smoking in the entire country.Once everyone gets used to the idea,all will be better off soon.The tobacco companies are fighting the idea like mad.They say nobody has proved that cigaretters are bad for you.They say as a matter of fact,the doctors hav e proved that a cigarette saved a person’s life after that person was shot.Other places under consideration are:the cold areas in Alaska,the Rocky Mountains in Colorado and the WhitewaterRiver in Arkansas.53.Smokers in the U.S. ________________ to light a cigarette now.A.find nowhereB.are not so freeC.have a rightD.have to travel a long way54.The smokers are not too nervous about the government banning smoking for they think ________________.A.it is not a good ideaB.it is still far awayC.they have right to smoke anywhereD.they may smoke at home55.The tobacco companies don’t like the idea because they ________________.A.want to save persons’ livesB.wish smokers to stay at homeC.wish smokers to feel easyD.want to improve their cigarettes56.Which is r ight about the writer’s opinion according to the passage?A.He thinks the government should help the smokers to find a proper place.B.None of the places in the passage is proper for the smokers.C.The places are too far away for the smokers to light up their cigarettes.D.Smokers are not welcome in the U.S.DLONDON(Reuters)—Organic fruit,delivered right to the doorstep.That is what Gabriel Gold prefers,and he is willing to pay for it.If this is not possible,the 26-year old computer technician will spend the extra money at the supermarket to buy organic food.“Organic produce is always better.”Gold said.“The food is free of pesticides(农药),and you are generally supporting family farms instead of large farms.And more often than that it is locally(本地)grown and seasonal,so it is more tasty.” Gold is one of the growing number of shoppers buying into the organic trend,and supermarkets across Britain are counting on more like him as they grow their organic food business.But how many shoppers really know what they are getting,and why are they willing to pay a higher price for organic produce?Market research shows that Gold and others who buy organic food can generally give clear reasons for their preferences—but their knowledge of organic food is far from completing.For example,amounts of pesticides can be used on organic products.And about three quarters of organic food in Britain is not local but imported(进口)to meet growing demand.“The demand for organic food is increasing by about one third every year,so it is a very fast-growing market,”said Sue Hock,a specialist in this line of business.57.Moreandmorepeople in Britain are buying organic food because_______.A.they are getting richerB.they can get the food anywhereC.they consider the food free of pollutionD.they like home-grown fruit58.Which of the following statements is true to the facts about most organic produce sold in Britain?A.It grows indoors all year round.B.It is produced outside Britain.C.It is grown on family farms.D.It is produced on large farms.59.What is the meaning of “the organic trend” as the words are used in the text?A.Growing interesting in organic food.B.Better quality of organic food.C.Rising market for organic food.D.Higher prices of organic food.60.What is the best title for this news story?anic Food —Healthy,or Just for the Wealthy?B.The Making of Organic Food in Britain.anic Food —to Import or Not?D.Good Qualities of Organic Food.第二节(共5小题,每小题2分,满分10分)根据短文内容,从下框的A~F 选项中选出能概括每一段主题的最佳选项。
